# This file is used by clang-format to autoformat paddle source code
|
||||
#
|
||||
# The clang-format is part of llvm toolchain.
|
||||
# It need to install llvm and clang to format source code style.
|
||||
#
|
||||
# The basic usage is,
|
||||
# clang-format -i -style=file PATH/TO/SOURCE/CODE
|
||||
#
|
||||
# The -style=file implicit use ".clang-format" file located in one of
|
||||
# parent directory.
|
||||
# The -i means inplace change.
|
||||
#
|
||||
# The document of clang-format is
|
||||
# http://clang.llvm.org/docs/ClangFormat.html
